GATE

Specification of Letters Patent.

Patented July so, 1907.

Application filed November 20, 1906. Serial No. 344,276.

To all whom 'it may concern:

Be it known that I, LORENZO D. I'IAILn, a citizen of the United States, residing at Kingsland, in the county of Llano, State ol Texas, have invented certain new and useful Improvements in Gates; and I do hereby declare the following to be a ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

"his invention is in line with that kind of gates that are provided with an upper and lower hinge, the latter being in the i'orm of a pivot stepped in a laterally shift-able bar to render the gate sell-opening.

The nature of my invention consists of improvements that simplify and cheapen the cost oi construction and render the shil'ting of the step entirely certain; and the invention further consists in improved means for unlatching the gate automatically.

The improvements embodied in the device are portrayed in the annexed drawings, forming a part of this specilication, in view of Which they will iirst be described in detail and then be pointed out in the subjoined claims.

Oi the said drawings z-,Figure l is a perspective view oi my invention. Fig. 2 is a detail sectional view through the latch post. Fig. 3 is a plan of the laterally shiitable pivot slide. Fig. 4 is a transverse section of the same.

Similar numerals of reference designate similar parts.

tially similar bar l2, at the latching end, the two upright bars being connected by lateral bars.

I3 designates the hinging post and l4 the latching post. The gate is hinged to the post 13 by means of a pintle l5 extending vertically from the top of the bar ll through the eye 16 of a bolt 16 extending through the post 13 and having nuts on both sides of the post to adjust it and the gate l0 with respect to the post. At the bottom oi the bar ll there extends vertically therefrom a oot-pintle 17 that is stepped in a slight recess I8 formed centrally in the upper lace of the bar 19 supported in an under-cut groove formed in a transversely arranged base-piece 20. The step-bar 19 is arranged to be moved longitudinally in its groove support in both directions, throwing the gate out of plum and so causing it to swing open by gravity in a well-known Way. I

As a means or moving the step-bar, I connect one end of a cord 2l to one end oi the step-bar 19, passing said cord back through an eye on one arm 22 of a crankrod pivoted at its inner distance upon a post 23 set in the ground at a suitable end from the gate. The cord 2l after engaging the said crank-lever is passed around a pulley on the hinge-stile and thenceover another pulley on the gate to the gate-latch 25. The rod 22 extends in line with the roadway that passes the gate and has a right angular extension 24 extending transversely across the track of the roadway. These means and their specific arrangement are established on both sides of the gate. The tension on the cord 2l is such as to keep the bar or rod 22 and its angular part 24 no1'- mally raised so that when the wheels oi' a vehicle are driven over the angular extension 24, they depress the free end of the rod 22, draw on the cord 2l and pull the slide 19 longitudinally toward the vehicle, move the hanging of the gate out of plumb and impart a tendency to the latter to swing open by gravity in a direction away from the approaching vehicle. The gate-post 14 is provided with a catch 26 with which the pivoted latch 25 on the gate is adapted to engage.

When the Wheel of a vehicle passes over either angular extension 24 it depresses the rod 22 with the effect oi drawing on the cord 27 and raising the latch from its engagement with its catch and allowing the gate t0 swing open.

The position ol the pintles l5 and 17 indirect line with the vertical bar ll renders the movement of the step slide 19 easy and certain; and this is an important feature of the improvement.

Ot course, the gate may have a different orm from that shown and other parts may be changed or varied in form and arrangement without departing from the gen eral nature or spirit of the invention.

What is claimed isz- 1. A self-opening gate having its vertical hinging bar provided with pintles extending in line with the bar, the

'upper pintle having a suitable hinge connection, a longitudinally movable step-bar provided with a socket in which the lower pintle is stepped, rods extending from the ends ot' the said step-bai' and movable means extended across the track of the drive-way with which the other ends of the rods are connected.

2. The combinationwith the vertical hinge-bar of a gate having :1 pintle extending from its lower end in line with the har, a base provided with a groove havingundercut sides, a stepbar constructedto slide in said groove into which bar the said pintle is stepped and means connected with the ends -of the step-bar to slide the same longitudinally by the engagement of the wheel of a vehicle therewith.

3. The combination with the vertical hingebar of a gate havingits lower hinge-pintle in line with the bar, of the sliding step-bar on which the pintle rests, and a basebar for supporting the step-bar.

In testimony whereof., I afx my signature, in presence of two Witnesses.

LORENZO D. HAILE.
